Telescoping auxiliary gun stock attachment for firearms

ABSTRACT

THIS TELESCOPING AUXILIARY GUN STOCK ATTACHMENT HAS A MOUNTING PLATE OR REARWARD BRACKET WHICH IS SECURED TO THE END OF THE REMAINING PORTION OF THE SHORTENED REGULAR GUN STOCK OF THE RIFLE OR OTHER FIREARM. EXTENDING FORWARD FROM THE MOUNTING PLATE WITH ITS AXIS OFFSET TO THE LEFT FROM THE AXIS OF THE RIFLE BARREL TO AVOID CONFLICT WITH THE MAGAZINE CARTRIDGE CLIP HOLDER IS AN ELONGATED TUBE TO THE FORWARD END OF WHICH IS SECURED AN UPWARDLYINCLINED AND ALSO SIMILARLY-OFFSET ROD OR FORWARD BRACKET, THE UPPER END OF WHICH IS SECURED TO THE FORWARD SLING SWIVEL OF THE FIREARM. TELESCOPINGLY MOUNTED WITHIN THE TUBE IS THE STEM OF AN AUXILIARY GUN STOCK HAVING A PERPENDICULARLY-BENT APPROXIMATELY D-SHAPED AUXILIARY BUTT LOOP. THE STEM IS AN ELONGATED ROD CARRYING A CROSS PIN WHICH PROJECTS THROUGH AND SLIDES IN AN ELONGATED SLOT IN THE TUBE AND IS NOTCHED AT TWO LOCATIONS TO RECEIVE THE DETENT LUG ON THE END OF A SPRING DETENT ARM TO HOLD THE AUXILIARY STOCK IN ITS EXTENDED AND RETRACTED POSITIONS RESPECTIVELY. THIS INVENTION ENABLES THE FIREARM TO BE PACKED INTO A SMALLER SPACE FOR TRANSPORTATION OF STORAGE THAN A CONVENTIONAL FIREARM.

Int. Cl. F41c 23/00 US. Cl. 42-72 10 Claims ABSTRACT OF THE DISCLOSURE This telescoping auxiliary gun stock attachment has a mounting plate or rearward bracket which is secured to the end of the remaining portion of the shortened regular gun stock of the rifle or other firearm. Extending forward from the mounting plate with its axis offset to the left from the axis of the rifle barrel to avoid conflict with the magazine cartridge clip holder is an elongated tube to the forward end of which is secured an upwardlyinclined and also similarly-offset rod or forward bracket, the upper end of which is secured to the forward sling swivel of the firearm. Telescopingly mounted within the tube is the stem of an auxiliary gun stock having a perpendicularly-bent approximately D-shaped auxiliary butt loop. The stem is an elongated rod carrying a cross pin which projects through and slides in an elongated slot in the tube and is notched at two locations to receive the detent lug on the end of a spring detent arm to hold the auxiliary stock in its extended and retracted positions respectively. This invention enables the firearm to be packed into a smaller space for transportation or storage than a conventional firearm.

In the drawings:

FIG. 1 is a side elevation of a firearm, particularly a bolt action repeating rifle, equipped with a telescoping auxiliary stock attachment, according to one form of the invention, with the auxiliary stock in its extended position;

FIG. 2 is a side elevation similar to FIG. 1, but with the auxiliary stock in its retracted position;

FIG. 3 is an enlarged side elevation, partly in vertical section, of the auxiliary gun stock shown in FIGS. 1 and 2, with a portion of the elongated rod or stem of the stock broken away to conserve drawing space;

FIG. 4 is a rear elevation looking in the direction of the arrows 4-4 in FIG. 3;

FIG. 5 is a vertical section taken along the line 5-5 in FIG. 3;

FIG. 6 is a fragmentary plan view looking downward at an angle indicated by the arrows 66 in FIG. 3; and

FIG. 7 is a cross-section taken along the line 7-7 in FIG. 3.

Referring to the drawings in detail, FIG. 1 shows a firearm, generally designated 10, for example a conventional bolt-action repeating rifle equipped with a telescoping auxiliary gun stock attachment 12 according to one form of the present invention. To attach the auxiliary gun stock attachment 12, the rearward portion of the rifle gun stock 14 behind the pistol grip portion 15 has been removed along a substantially vertical facing or surface 16. The rifle 10 is equipped with a conventional bolt-action mechanism 18 receiving cartridges from an arcuately curved hollow clip magazine 20 disposed immediately below the cartridge chamber (not shown) in the rearward end of the rifle barrel 22. The forestock 24 and the foregrip 26, usually of wood, surround the rearward portion of the rifle barrel 22 and are held in assembly at their forward ends by a sling swivel 28 having the usual clamping bolt 30 at its lower end. The bolt-action mechanism '18, as usual, is actuated by the conventional trigger 32 within the trigger guard 34.

3,570,162. Patented Mar. 16, 1971 The telescoping auxiliary gun stock attachment 12 includes a mounting plate or rearward bracket 36 secured as by screws or other fasteners 38 to the surface or facing 16 of the remainder of the rifle gun stock 14. Secured as by welding to the forward face of the mounting plate 36 is a swivel boss 40, the upper and lower ends of which are provided with sockets or blind holes 42 in which are seated and pivotally mounted the opposite end portions 44 of an approximately D-shapedl rearward sling swivel 46. The mounting plate 36 is vertically elongated with a leftward offset lower end portion 48 containing a hole 50 which is welded or otherwise secured the rearward end of an elongated supporting tube 52. Mounted in the forward end of the supporting tube 52 is the rearward end or shank 54 of a leftwardand verticallyoifset forward bracket 56 consisting of a bent rod having an intermediate portion 58 inclined at a compound or skew angle both to the horizontal and to the vertical and having a tapered upper portion 60 with a flattened end portion 62 containing a horizontal hole 64. The flattened end portion 62 fits between the two opposing lower ends of the forward sling swivel 28 and is clamped in position by the clamping bolt 30 passing through the hole 64. Instead of the separate forward bracket 56, the invention contemplates that the forward end portion of the tube 52 will be similarly bent upward and leftward and similarly secured to the forward sling swivel.

The supporting tube 52 is provided with a pair of aligned elongated longitudinal slots 68 (FIGS. 1, 2 and 7) in which ride the opposite ends of a stop pin 70, the intermediate portion of which passes through and is secured in the stem or auxiliary stock rod 72 of the auxiliary stock, generally designated 74. The rearward end of the stock rod or stem 72 terminates in an upstanding approximately D-shaped auxiliary butt 76 in the form of a rectangular loop (FIG. 4) including a lower horizontal arm 78, a vertical arm 80, an upper horizontal arm 82 and a vertical end portion 84 separated by a gap 86 from the rod or stem 72. The plane of the auxiliary butt loop 76 is substantially perpendicular to the axis of the rod or stem 72. The latter is provided with longitudinally-spaced forward and rearward notches 88 and 90 respectively (FIG. 1) which are selectively engaged by the upturned detent lug 92 on an angle arm 94 which in turn is riveted or otherwise secured to the leaf spring 96 of a spring detent, generally designated 98, the forward end of which is riveted or otherwise secured as at 100 to the lower side of the supporting tube 52.

In the operation of the invention, let it be assumed that the parts of the auxiliary gun stock attachment 12 are in the telescoped or retracted position shown in FIG. 2, such as for transportation or storage, and that the user wishes to prepare it for firing. To do so, he grasps the butt loop 76 and pulls on it while he pushes downward on the detent spring 96 to withdraw the detent lug 92 from the rearward notch 90. With the auxiliary stock thus freed for extension movement, he continues to pull rearwardly on the butt loop 76 until the forward notch 88 arrives in alignment with the detent lug 92, whereupon the force of the leaf spring 96 pushes the lug 92 into the forward notch 88 and locks the auxiliary stock 74 in its extended position FIG. (1). The firearm 10 is then used in the ordinary manner.

To retract the auxiliary stock 74, the user reverses the foregoing procedure by pressing downward upon the leaf spring 96 to withdraw the detent lug 92 from the forward notch 88 while he presses forward against the butt loop 76, causing the rod or stem 72 to slide into the supporting tube 52 until the detent lug 92 is again urged into the rearward notch 90 by the leaf spring 96. The parts are now in the positions shown in FIG. 2. Meanwhile, the

action of-the'stop pin 70 not only serves to limit the sliding motion of-the-rodor ste-m-72 but also prevents relative twisting or rotation between it and the supporting tube 52.
